The therapy uses prime editing, a CRISPR-based technology developed by David Liu, to insert two missing DNA letters into blood cells, addressing CGD which causes life-threatening infections and inflammation 1 . This biologics license application (BLA) follows 'breakthrough' Phase 1/2 data for PM359 and aims for accelerated approval after final FDA alignment 3 . The move tests the FDA's commitment to speeding gene-editing treatments amid recent scrutiny over neurological gene therapies 1 .
